Abstract:
As a result of thermal and electrical conditions, insulating oil utilized in electrical transformers decomposes over time, forming light gases that dissolve into the transformer’s oil. Measuring the levels of the DG found in the insulating oil is one way to monitor the health of the transformer. If these gases are analyzed on a routine basis, a failing transformer can be identified and replaced without a power loss or the potential of a serious explosion. PerkinElmer’s Transformer Oil Gas Analyzer (TOGA) system, using a Clarus® 590 GC coupled with a Turbo Matrix™ Headspace sampler, has the capabilities to perform ASTM D3612 Method C for the detection of H2, O2, N2, CH4 (methane), CO, CO2, C2H2 (acetylene), C2H4(ethylene), C2H6(ethane), C3H6 (propylene) and C3H8(propane). This poster will give a general overview of multiple column sets available to perform the analysis and evaluate the selectivity, run time and resolution of each column set.
